Abstract
The cell adhesion molecule TAG1 has been identified as the ligand that induces
-amyloid precursor protein (APP) processing and signalling, resulting in the inhibition of neurogenesis. These findings demonstrate a critical role of TAG1–APP signalling in brain development and suggest the potential involvement of TAG1 in adult neuroplasticity and pathogenesis of Alzheimer's disease.
